    Notes: [Auszug] Our two sediment cores were collected during the Fram-I expedition11. Core Fram-I/4 was raised from the Fram Basin (8429'56" N, 0858'39" W, water depth 3,820 m) and core Fram-I/7 from the northern flank of Nansen Ridge (8352'38" N, 0657'17" W, water depth 2,990m) (Fig. 1). The stable isotope ...

    Notes: [Auszug] THE past two years have seen a revolution in our thinking on climate variability, largely because of the signs of ultra-fast climate oscillations found in deep ice cores. But the ice-core records for part of the last interglacial period disagree, and other evidence for the variability ...

    Notes: [Auszug] Evidence for abrupt climate changes on millennial and shorter timescales is widespread in marine and terrestrial climate records. Rapid reorganization of ocean circulation is considered to exert some control over these changes, as are shifts in the concentrations of atmospheric greenhouse ...

    Global change: Monsoon linkages (2003)
    Nature Publishing Group
    In:  Nature, 421 (6921). pp. 324-325.
    Details
    Publication Date: 2016-07-19
    Description: An excellent sediment record from the Arabian Sea traces recent patterns in the activity of the Asian monsoon. It reveals both variability in monsoon strength and links with climatic events elsewhere. The monsoon is the main determinant of environmental conditions over much of Asia, and so affects the most densely populated region on Earth. Differential heating of the north Indian Ocean and the northwest Pacific, and of the Asian land-mass, cause the seasonal reversal of monsoon winds. In summer, these winds blow northwards over the northern Indian Ocean, carrying huge amounts of moisture over the neighbouring land. The ensuing heavy rainfall can have devastating consequences for human life and livelihood. Conversely, agriculture in Asia depends on monsoon rains; and the seasonal upwelling of nutrient-laden subsurface waters, driven by monsoon winds, is essential to the success of coastal fisheries.

    Suborbital intermediate water variability inferred from paired benthic foraminiferal Cd/Ca and δ13C in the tropical West Atlantic and linking with North Atlantic climates (2002)
    Elsevier
    In:  Earth and Planetary Science Letters, 200 (1-2). pp. 191-205.
    Details
    Publication Date: 2016-07-15
    Description: Paired benthic Cd/Ca and δ13C records have been generated along core M35003 in the western tropical Atlantic. Decreased glacial water column dissolved cadmium (Cdw) and increased benthic δ13C indicate enhanced ventilation with nutrient-deplete intermediate waters, in line with similar inferences from other North Atlantic mid-depth records. An abrupt early deglacial δ13C collapse that is associated with a marked positive Cdw anomaly indicates a transient collapse of mid-depth ventilation from North Atlantic sources, conceivably in conjunction with the H1 meltwater anomaly. The Cdw record displays fine-scale fluctuations that mimic the Greenland Dansgaard/Oeschger (D/O) cycles and show decreased Cdw during stadials. This pattern is opposite to Cdw variations in a deep water record from Bermuda Rise that display increased Cdw concentrations during stadials. The divergent pattern between mid-depth and deep water Cdw records indicates millennial-scale switches between deep and shallow convection in the glacial North Atlantic, at the pace of the D/O climatic cycles. Several high-amplitude anomalies occur in the Cdw record that reach levels similar to those observed today in the North Pacific. While a substantial nutrient increase in the mid-depth North Atlantic cannot be ruled out during these events, changes of pore water chemistry and Cd/P fractionation during biological uptake offer alternative scenarios to explain the peak Cdw maxima.

    Quantitative estimate of the paleo-Agulhas leakage (2014)
    AGU (American Geophysical Union) | Wiley
    In:  Geophysical Research Letters, 41 (4). pp. 1238-1246.
    Details
    Publication Date: 2017-04-10
    Description: The Indian-Atlantic water exchange south of Africa (Agulhas leakage) is a key component of the global ocean circulation. No quantitative estimation of the paleo-Agulhas leakage exists. We quantify the variability in interocean exchange over the past 640,000 years, using planktic foraminiferal assemblage data from two marine sediment records to define an Agulhas leakage efficiency index. We confirm the validity of our new approach with a numerical ocean model that realistically simulates the modern Agulhas leakage changes. Our results suggest that, during the past several glacial-interglacial cycles, the Agulhas leakage varied by ~10 sverdrup and more during major climatic transitions. This lends strong credence to the hypothesis that modifications in the leakage played a key role in changing the overturning circulation to full strength mode. Our results are instrumental for validating and quantifying the contribution of the Indian-Atlantic water leakage to the global climate changes.
